Question 1174401: Assuming that the samples come from normal distributions, find the margin of error given the following:
A.n=10, sample mean= 28, s=4.0, 90% confidence
B.n= 16, sample mean=50, s=4.2, 95% confidence

Hi
Note Table Below:
ME =
A.n=10, sample mean= 28, s=4.0, 90% confidence
 ME =
28 - ME <  < 28 + ME

B.n= 16, sample mean=50, s=4.2, 95% confidence
   ME =
50 - ME <  < 50 + ME

Wish You the Best in your Studies.

 = CI	z = value
90%	z =1.645
92%	z = 1.751
95%	z = 1.96
98%	z = 2.326
99%	z = 2.576
